Made a few more miles with the new setup. All in all I think near 500 miles or so.
Had some minor issues like a wastegate gasket blowing out and a few bolt coming loose but most has been sorted out now.
The boost curve needs some a djustemnt. I will receive a new chip tomorrow with higher boost settings over the mid rpm band. This way the torque will be back on the level where it was with the T3/T04 turbo.
The higher rpm band is extreme. The car just keeps pulling all the way to 7200 RPM.
At this moment there still is a small boost dip near 5200 rpm but after that the boost just keeps building up to 18 psi at 7000 RPM.
Made 2 round trips into Germany last week and had the cat flatout for over 20 miles on a nice piece of Autobahn called the A31. End speed was 174 mph before I had to exit the Autobahn. Was held up by a BMW Bangle 530d doing 152 mph for some time but managed to overtake and leave him behind in the mirror.
So, now I hope the midrange will be on par again with the new chip.
ordered a rear spoiler finally after experiencing some lift at higher speeds..
So, to solve the "between the ears, problem I decided to install it regardless.
Unfortunately the car loses a bit of it's sleeper image.
